If the Windows operating system ever notifies you about a weak Wi-Fi signal, it probably means that your connection isn't as fast or as reliable as it could be. Worse, you might lose your connection entirely in some parts of your home. If you want to boost the signal for your wireless network (WLAN), try some of these tips for extending your wireless range and improving your wireless network speed and performance.
1. Position your wireless router, modem router, or access point in a central location
When possible, place your wireless router, wireless modem router (a DSL or cable modem with a built-in wireless router), or wireless access point (WAP) in a central location in your home. If your wireless router, modem router, or access point is against an outside wall of your home, the signal will be weak on the other side of your home. If your router is on the first floor and your PC or laptop is on the second floor, place the router high on a shelf in the room where it is located. Don't worry if you can't move your wireless router, because there are many other ways to improve your connection.
2. Move the router off the floor and away from walls and metal objects (such as metal file cabinets)
Metal objects, walls, and floors will interfere with your router's wireless signals. The closer your router is to these obstructions, the more severe the interference, and the weaker your connection will be.
3. Replace your router's antenna
The antennas supplied with your router are designed to be omnidirectional, meaning that they broadcast in all directions around the router. If your router is near an outside wall, half of the wireless signals will be sent outside your home, and much of your router's power will be wasted. Most routers don't allow you to increase the power output, but you can make better use of the power. If your router’s antenna is removable, you can upgrade to a high-gain antenna that focuses the wireless signals in only one direction. You can even aim the signal in the direction you need it most. Consider a Linksys high-gain antenna—they’re powerful and easy to install. Or shop for other high-gain antennas.
